Description

Technical Field

[0001] The utility model relates to the technical field of floor slab construction, in particular to a supporting device. Background Art

[0002] When pouring floor concrete for high-rise buildings, the height of the floor formwork is high, while the height of the slurry outlet of the truck pump is limited, so the truck pump cannot be extended to the height of the formwork for pouring; when pouring floor concrete for buildings with complex surrounding environments, the truck pump cannot be close to the building, and the slurry outlet cannot be extended to the position of the formwork for pouring. However, the concrete placing boom can be placed directly on the floor formwork to be poured for pouring, which can solve the above problems and is more convenient to use. However, during operation, the concrete placing boom will generate a large degree of vibration, which will drive the floor formwork to vibrate together, increase the density of the concrete after pouring, and increase the lateral pressure of the concrete on the formwork. The formwork is prone to bursting or deformation due to its inability to withstand the lateral pressure, resulting in the floor strength not meeting the requirements, affecting the construction quality.

[0003] The prior art discloses a vibration reduction support mechanism and a material placing machine, such as Figure 1 As shown, the vibration reduction support mechanism includes a base 01, a support assembly 02 and a supporting assembly 03. The base 01 is placed on the lower floor, the support assembly 02 is installed on the base 01, and the supporting assembly 03 is installed on the support assembly 02 and is located below the template 04. Among them, the supporting assembly 03 includes a vibration reduction plate 031 and a supporting plate 032, the supporting plate 032 is connected to the end of the support assembly 02 away from the base 01, the vibration reduction plate 031 is installed above the supporting plate 032 and is located below the template 04, and the support leg 05 of the concrete placing machine is fixed above the template 04 and is arranged directly opposite to the vibration reduction plate 031. By fixing one end of the vibration reduction support mechanism on the lower floor and the other end fixed below the template 04 of the upper floor, the vibration generated by the concrete placing machine during operation can be partially offset by the elastic deformation of the vibration reduction plate 031 and by being transmitted to the lower floor, thereby reducing the vibration effect of the concrete placing machine on the template 04. However, since the support legs 05 of the concrete placing machine are in direct contact with the template 04, the vibration reduction effect of the vibration reduction support mechanism is relatively weak, and the vibration influence of the concrete placing machine on the template is still significant. Utility Model Content

[0022] In an optional embodiment, the second support member is a retractable structure.

The specific number of the first support members 2 and two or three second support members 3 is determined according to the actual situation, and no excessive restrictions are made here.

[0058] The second support member 3 in this embodiment is a retractable structure. By setting the second support member 3 as a retractable structure, the height of the support device can be adjusted according to the height between the upper floor template 1 and the lower floor, so as to facilitate support and prevent the top of the second support member 3 from contacting the upper floor template 1. As a convertible embodiment, the second support member 3 can also be a plurality of support rods, and a suitable number of support members can be selected and fixed according to the height between the upper floor template 1 and the lower floor to achieve the effect of adjusting the height of the support device.

By detachably connecting the first connecting member 33 and the second connecting member 34 to the telescopic body 32, it is convenient to replace parts; by threading the first connecting member 33 and the second connecting member 34 to the telescopic body 32, the length of the supporting device can be adjusted more accurately. As a convertible embodiment, it is also possible that the side walls of the second connecting part 332 and the fourth connecting part 342 are both provided with a plurality of through holes, and the second connecting part 332 and the fourth connecting part 342 are respectively inserted into the two ends of the telescopic body 32 and fixed by bolts.

[0064] Specifically, a fifth connection part 321 and a sixth connection part 322 are respectively provided at both ends of the telescopic body 32, and the fifth connection part 321 and the sixth connection part 322 are both surrounded by square steel and steel plate, one end of the square steel is welded with a steel plate, and the other end is welded to the end of the telescopic body 32, a first through hole is provided on the steel plate of the fifth connection part 321, and a second through hole is provided on the steel plate of the sixth connection part 322.

[0065] like Figure 3 As shown, a vibration damper 5 is provided above the first support member 2 in this embodiment. The vibration damper 5 is a vibration damping rubber pad, and the size and thickness of the rubber pad are the same as those of the first support member 2. By providing the vibration damper 5 above the first support member 2, the vibration effect of the material placing machine 7 on the support device can be reduced, thereby increasing the service life of the support device, and also reducing the vibration effect of the material placing machine 7 on the lower floor. As a convertible embodiment, the vibration damper 5 can also be a silicone pad or other structure capable of vibration damping.

[0066] like Figure 3As shown, two adjacent second support members 3 are connected by a third support member 6.

By setting the third support member 6 between the second support members 3, multiple second support members 3 can be connected as a whole, and the longitudinal vibration generated by the fabricating machine 7 can be more evenly dispersed to each second support member 3, which can avoid the second support members 3 being subjected to different vibration effects when the center of gravity of the fabricating machine 7 and the center of gravity of the support device are not in the same straight line, resulting in a large difference in the service life of the second support members 3; secondly, since the third support member 6 connects the second support members 3 as a whole, the lateral vibration generated by the fabricating machine 7 will be hindered by the third support member 6 after being dispersed to the second support member 3, which can reduce the lateral vibration of the support device to improve the strength and stability of the support device. As a convertible embodiment, it is also possible that only one or two third support members 6 are provided, and the number of third support members 6 is determined according to actual conditions, and no excessive restrictions are made here.

[0067] In the circumferential direction, two adjacent third support members 6 are staggered. By staggering the third support members 6, it is possible to prevent the second support members 3 in the same horizontal plane from being cracked due to local force concentration.
